The Right System for East Texas Winters
Heat Pump Services
in Longview, TX
A heat pump does not make heat — it moves it, which is why it can deliver several times more heating energy than the electricity it consumes. That advantage holds across almost the entire East Texas winter, which makes this one of the better climates in the country for the technology and one where a furnace is often the more expensive habit.

What We Do
Heat Pump Services
Because the same machine handles both seasons, a heat pump technician needs to understand cooling and heating as one system. That is exactly how we have worked since 1957.
Heat Pump Installation
New systems and conversions from furnace or resistance heat, sized by load calculation rather than matched to whatever was there before.
- Load-Calculated Sizing
- Furnace Conversions
- Bryant Factory Authorized
- Financing Available
Maintenance
A heat pump runs year round rather than seasonally, so it accumulates roughly twice the hours of a cooling-only system and benefits from service accordingly.
- Twice-Yearly Recommended
- Refrigerant Charge
- Defrost Operation
- Auxiliary Heat Behaviour
Dual-Fuel Systems
A heat pump paired with a gas furnace that takes over only in genuinely cold weather. The lowest running cost available if you have gas service.
- Heat Pump Plus Gas Backup
- Automatic Changeover
- Lowest Operating Cost
- Best of Both Systems
Ductless Mini-Splits
Heat pumps without ductwork, for additions, converted garages, sunrooms and any room the existing system was never designed to reach.
- No Ductwork Needed
- Room-by-Room Control
- Additions & Conversions
- Very High Efficiency
Cooling Season Service
In summer a heat pump is simply an air conditioner. All our cooling services apply to it without qualification.

How They Work
Understanding Your Heat Pump
Most heat pump complaints we attend are not faults. They are the system behaving normally in ways nobody explained at installation.
Why the air feels cooler than a furnace
▾
A heat pump delivers air at roughly 90 to 100 degrees, which is warmer than the room but cooler than skin temperature — so it feels cool on your hand even while it is heating the house effectively. A gas furnace delivers air well above skin temperature, which feels dramatically warmer. This is the single most common reason people believe a working heat pump is broken, and it is worth knowing before the first cold week rather than after.

The defrost cycle and the steam that alarms people
▾
In cold damp weather frost forms on the outdoor coil, and periodically the system briefly reverses to melt it. During those few minutes the indoor air goes cool, the outdoor unit may steam impressively, and it can look exactly like something failing. It is normal and it is over in five to fifteen minutes. What is not normal is defrost running constantly, or ice that never clears.

Auxiliary heat and where winter bills come from
▾
When a heat pump cannot keep up alone, electric resistance strips engage to help. Those strips are essentially large space heaters and cost several times as much to run. In East Texas they should engage rarely. If your bill jumped and the thermostat has been showing auxiliary or emergency heat, the causes are usually a set-back schedule demanding big recoveries, a low refrigerant charge or a defrost fault — all worth diagnosing rather than paying for.

Why this climate suits heat pumps particularly well
▾
Heat pump efficiency falls as outdoor temperature drops, and in genuinely cold regions you need substantial backup for a large part of the season. East Texas spends the overwhelming majority of its winter in the range where a heat pump is very efficient, with only occasional hard freezes. That combination — long mild winters plus a demanding cooling season the same equipment handles — is close to ideal.
Heat Pump Installation →Normal or a Fault?
What is expected behaviour and what is not.
| What You Notice | Normal? | Notes |
|---|---|---|
| Air feels warm but not hot | Normal | Heat pumps deliver cooler air than furnaces |
| Outdoor unit steams in cold damp weather | Normal | Defrost cycle — lasts minutes |
| Cool air indoors for a few minutes | Normal | Defrost cycle, then heating resumes |
| Auxiliary heat on constantly | Not normal | Diagnose — charge, defrost or thermostat |
| Ice on the outdoor unit that never clears | Not normal | Defrost control fault — call us |

How It Works
How We Work
Whether it is a fault or a question about behaviour, we would rather explain than replace.
1
Describe What It Is Doing
A good share of heat pump calls resolve into normal behaviour that nobody explained. We will tell you if that is yours.
2
Test Both Modes
It is one machine doing two jobs, so we verify heating and cooling operation rather than only the season you called about.
3
Check Auxiliary Heat Behaviour
How often the strips engage is where most unexpected winter bills in this area actually come from.
4
Flat Price and Repair
You approve a figure first, and we explain what failed and what it means for the system.
Worth a Call
Signs Your Heat Pump Needs Attention
Some of what looks alarming is normal. These are the ones that are not.
Auxiliary or emergency heat showing constantly
In this climate the strips should engage rarely. Constant operation is a fault, and an expensive one to leave alone.
Ice on the outdoor unit that never clears
The defrost cycle is not working. Left alone this damages the outdoor coil and eventually the compressor.
Cool air for more than about fifteen minutes
A short cool spell during defrost is normal. Sustained cool air while calling for heat is not.
A winter bill well above last year
Almost always auxiliary heat running more than it should, which is diagnosable and often inexpensive to correct.
Heating when set to cool, or the reverse
A reversing valve problem. The system is physically capable of both and is choosing wrong.
Loud or unusual noises from the outdoor unit
Some sound at defrost changeover is normal. Grinding, screeching or sustained rattling is not.
Common Heat Pump Faults
Low refrigerant charge
Reduces heating capacity, so the system leans on auxiliary heat far more. Usually indicates a leak rather than consumption.
Defrost control faults
Either failing to defrost, leaving ice on the coil, or defrosting far too often and wasting energy every cycle.
Reversing valve failure
The component that lets one machine do both jobs. When it sticks the system delivers the wrong season.
Thermostat set-back schedules
Large night-time set-backs force big morning recoveries, which is exactly when a heat pump calls in expensive auxiliary heat.

Common Questions
Heat Pump Questions from Longview Homeowners
What people ask most often about heat pumps in East Texas.
Do heat pumps work well in East Texas?
▾
Very well — this is close to an ideal climate for them. Heat pump efficiency declines as it gets colder, and in genuinely cold regions you need substantial backup heat for much of the season. East Texas spends the overwhelming majority of its winter in the range where a heat pump is highly efficient, with only occasional hard freezes, and the same equipment handles a long demanding cooling season.
Why does my heat pump blow air that feels cool?
▾
Because heat pump supply air is around 90 to 100 degrees — warmer than the room, but cooler than your skin, so it feels cool on your hand. A gas furnace delivers air well above skin temperature, which feels dramatically hotter. The heat pump is heating your house perfectly well; it just does it with a larger volume of gently warm air rather than a smaller volume of hot air.
What is auxiliary heat and why did my bill go up?
▾
Auxiliary heat is a set of electric resistance strips that engage when the heat pump alone cannot maintain temperature. They work, but they cost several times as much to run — effectively large space heaters. In this climate they should engage rarely. If your bill jumped, the usual causes are a thermostat set-back demanding large recoveries, a low refrigerant charge or a defrost fault, and all three are diagnosable.
My outdoor unit is steaming and ice is melting off it. Is that bad?
▾
That is the defrost cycle and it is entirely normal. In cold damp weather frost accumulates on the outdoor coil, and the system periodically reverses briefly to melt it — producing steam that can look quite dramatic. It lasts a few minutes and then heating resumes. What is not normal is ice that never clears, or defrost running almost continuously.
Should I use the "emergency heat" setting when it is very cold?
▾
No — and this setting causes a lot of unnecessary expense. Emergency heat switches the heat pump off completely and runs only the resistance strips, which is the most expensive way to heat your home. It exists for when the heat pump itself has failed and you need heat until a technician arrives. On a cold night the heat pump plus its normal auxiliary staging is both cheaper and perfectly capable.
How long do heat pumps last?
▾
Typically 12 to 15 years here, a little less than a cooling-only system would manage because it runs in both seasons rather than one. Annual or twice-yearly maintenance makes a real difference to reaching the upper end of that, particularly keeping refrigerant charge correct — a system running slightly undercharged leans on expensive auxiliary heat and works harder in both seasons.
Repair, installation and the cooling side each have their own page.
